Car-axle lubricator



UNTTED STATES PATENT OEEicE.

CHESTER D. FLYNI, OF BROOKLYN, NEW YORK.

CAR-AXLE LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 228,337, dated June 1,1880.

Application filed April 2:2, 1880.

To all whom it may concern Be it known that I, CHESTER D. FLYNT, acitizen of the United States, residing at Brooklyn, in the county ofKings and State of New York, have invented new and useful Improvementsin Oar-Axle Lubricators, of which the following is a specification.

This invention relates to the construction of pads for lubricating thejournals of car-axles; and it consists in a pad in which are combined acovering of sheep-skin or other skin of alike nature with the wool leftthereon, such skin being perforated for the passage of oil, and astuffing of wool, hair, sponge, or other absorbent and elastic material,so that while this pad is extremely durable it is an efl'ective mediumfor lubricating a journal, besides keeping the latter free ofimpurities.

This invention is illustrated in the accompanying drawings, in which-Figure 1 shows the pad, in cross-section, located in a journal-box. Fig.2 is a rear view of the covering spread out to show more clearly itsperforations.

Similar letters indicate corresponding parts.

The letter A designates the covering of the pad, having perforations b,and O the stuffing.

In carrying out my invention I take a piece of sheep-skin or any otherskin of a similar nature with the wool left thereon and out the same toa shape suitable for producing a pad of the desired form, at the sametime perforating the skin at divers points with holes of round, oblong,or any other shape. I then join the edges of the skin by stitches orother suitable means, leaving an opening for the introduction of thestuffing, whereupon I stuff the bag or covering thus obtained with wool,hair, sponge, or other absorbent and elastic material. I then close theopening through which the stuffing was introduced, when the Whole isready for use.

In applying the pad to use it is placed on the bottom of a journal-box,so as to impinge against thejournal, as shown in Fig. 1, its diameter orthickness being gaged appropriately for this purpose. If the journal-boxis then supplied with oil, the oil is immediately ab- (No model.)

sorbed or sucked up bythe pad, and the latter is thoroughly permeatedtherewith, so as to lubricate the journal in an effective manner, theoil which is wiped off the pad by the journal being at once replacedwith fresh oil by suction.

A It is a well-known fact that wool is a superior conductor ofoil,whileitis also leastliable to take fire, compared to the waste nowcommonly used in journal-boxes, and hence that material is peculiarlyadapted to a lubricatingpad.

.Another advantage of the wool is that it acts as a wiper to keep thejournal free of impurities, while the skin carrying the wool renders thewhole extremely durable.

.In some cases I attach to the pad a string or band, for convenience ofhandling.

If desired, the wool may be shorn from the skin-covering on that part orside of the pad which is out of contact with the journal, or a cheapmaterial, such as leather burlaps, may be inserted at that place.

A good result is obtained by coating the bearing surface of my pad withtalc, soapstone, plumbago, or other similar material.

It will be seen that as the pad takes up the oil from the bottom of thejournal-box it swells or expands, and hence the pad at once adaptsitself to the journal without regard to the size or the shape of thepad.

What I claim as new, and desire to secure by Letters Patent, is

The lubricating-pad herein described, consisting of a covering ofsheep-skin or other skin of a like nature with the wool left thereon,such skin being perforated for the passage of oil, and a stuffing ofwool, hair, sponge, or other absorbent and elastic material,substantially as shown and described.

In testimony whereof I have hereunto set,

my hand and seal in the presence of two subscribing witnesses.
